Trajectory detection and feedback system
First Claim
1. A system, comprising:
- at least one sensor configured to measure a motion of a basketball in free flight toward a basketball hoop during a basketball shot and to provide sensor data indicative of the measured motion;
a sound projection device; and
an electronic device configured to determine, based on the sensor data, an angle of a trajectory of the basketball when the basketball is proximate to the basketball hoop during the basketball shot, the electronic device further configured to automatically generate, based on the determined angle, feedback information associated with the motion of the basketball during the basketball shot and to automatically output the feedback information in an auditory format via the sound projection device in response to the basketball shot, wherein the feedback information is indicative of the angle.

Abstract
A disclosed device provides a trajectory detection and feedback system. The system is capable of detecting one or more moving objects in free flight, analyzing a trajectory of each object and providing immediate feedback information to a human that has launched the object into flight, and/or one or more observers in the area. In a particular embodiment, a non-intrusive machine vision system that remotely detects trajectories of moving objects may be used to evaluate trajectory parameters for a basketball shot at a basketball hoop by a player. The feedback information, such as a trajectory entry angle into the basketball hoop and/or an entry velocity into the hoop for the shot, may be output to the player in an auditory format using a sound projection device. The system may be operable to be set-up and to operate in a substantially autonomous manner.

6. A system, comprising:
-
at least one sensor configured to measure motions of at least one basketball in free flight toward a basketball hoop during a plurality of basketball shots by at least one user toward the basketball hoop during a basketball training session for the at least one user and to provide sensor data indicative of the measured motion, the plurality of basketball shots including a first basketball shot toward the basketball hoop and a second basketball shot toward the basketball hoop, wherein the first basketball shot and the second basketball shot are consecutive during the basketball training session for the at least one user; a sound projection device; and an electronic device configured to determine, based on the sensor data, an angle of a trajectory of the basketball when the basketball is proximate to the basketball hoop during the first basketball shot, the electronic device further configured to automatically generate feedback information associated with the motion of the basketball during the first basketball shot and automatically output the feedback information in an auditory format via the sound projection device between the first and second basketball shots in response to the first basketball shot, wherein the feedback information output in the auditory format via the sound projection device between the first and second basketball shots indicates the angle. - View Dependent Claims (7, 8, 9, 10, 23)

16. A method, comprising:
-
measuring with at least one sensor a motion of a basketball in free flight toward a basketball hoop during a first basketball shot; providing sensor data indicative of the measured motion; determining, with an electronic device based on the sensor data, an angle of a trajectory of the basketball when the basketball is proximate to the basketball hoop during the first basketball shot; automatically generating, with the electronic device based on the angle, feedback information associated with the motion of the basketball during the first basketball shot; and automatically outputting the feedback information in an auditory format with a sound projection device in response to the first basketball shot, wherein the feedback information is indicative of the angle. - View Dependent Claims (17, 18, 19, 20, 21)
